<p>Hi md,</p>
<p>Linking with C files works just fine. No problem with that. However I would like to link regular FPC object files instead. Please see the three files I attached in my first email. For some reason the linker could not find the implemented procedure. So the question is, how to modify the implementation unit so everything works.</p>
<p>Regards, Darius</p>

<p>Hi,</p>
<p>I was wondering if it's possible to link FPC object files by using the $Link directive? At least I have troubles in getting this to work and therefore I'm asking here. Please consider the minimal example I have attached to this email.</p>
<p>When linking the object file that implements the test_proc procedure I get the following compiler output:</p>
<p>Hint: Start of reading config file C:\lazarus\fpc\2.6.2\bin\x86_64-win64\fpc.cfg<br /> Hint: End of reading config file C:\lazarus\fpc\2.6.2\bin\x86_64-win64\fpc.cfg<br /> Free Pascal Compiler version 2.6.2 [2014/02/28] for x86_64<br /> Copyright (c) 1993-2012 by Florian Klaempfl and others<br /> Target OS: Win64 for x64<br /> Compiling test.pp<br /> Linking test.exe<br /> test.pp(8,1) Error: Undefined symbol: TEST_INT_TEST_PROC<br /> test.pp(8,1) Fatal: There were 1 errors compiling module, stopping</p>
<p>What is needed in the test_impl.pas file so the linker can find the implemented function? Do I need to create a library and export the function perhaps?</p>
<p>Regards, Darius Blaszyk</p>
